Abstract

The invention provides a combined nut capable of effectively preventing looseness. The combined nut comprises a first nut and a second nut which are engaged with each other; the first nut comprises afirst body part, an outer cylinder part and a reducing part connected in sequence; a continuous or discontinuous first bulge is formed in the circumferential direction on the outer surface of the outer cylinder part; the second nut comprises a second body part; a reducing hole and a cylindrical hole are sequentially formed in one end, matched with the first nut, of the second body part; a second bulge corresponding to the first bulge in position is arranged on the inner surface of the cylindrical hole; and a continuous or discontinuous device is arranged in the circumferential direction on thesecond bulge along the inner surface of the cylindrical hole. The combined nut capable of effectively preventing looseness, provided by the invention, is simple in structure, has a good looseness preventing effect, and can never loosen in the environments of vibration, impact and variable load.

Description

technical field [0001] The invention belongs to the field of fasteners, in particular to an effective anti-loosening combined nut. Background technique [0002] Fasteners are a type of mechanical parts used for fastening connections and are widely used. They can be seen in various types of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters, etc. Various fasteners. The purpose of fasteners is fastening. Once the fasteners loosen or fall off due to factors such as vibration and impact, it may cause equipment and machinery to lose their functionality, disintegrate, and even endanger personal safety. At present, more than 80% of the current mechanical equipment accidents are caused by the loosening of fasteners. [0003] In order to avoid various problems caused by the loosening of fasteners, technicians from various countries have continued to research and develop, and later there have been many methods to further impro...
